The narrator draws on the reader's preconceived notions about fighting with the phrase "manly warfare." Ender is aware of these "unspoken" rules, like "Don't hit someone who is down," but he deliberately defies them. This appeals to Colonel Graff: Ender ignores convention in order to win.

3.

We're the wicked witch. We promise gingerbread, but we eat the little bastards alive.

Colonel Graff is blunt and darkly comedic about his role in recruiting children into the International Fleet. Here he alludes to the fairy-tale "Hansel and Gretel," in which a witch tempts children with a house full of gingerbread so she can eat them. Graff tempts children with glamorous stories about International Fleet, but their experience is traumatic, and their lives are changed forever. However, Graff does not lie to or tempt Ender. He is honest about the challenges of Battle School.

4.

We might both do despicable things, Ender, but if humankind survives ... we were good tools.

Graff tells Ender their suffering may ensure humanity's survival. This may be his honest perception of the risks, but he is also manipulating Ender. If Graff is talking about humanity's survival, Ender can hardly complain about loneliness.

5.

Adults are the enemy, not the other armies. They do not tell us the truth.

Dink, Ender's toon leader, is a teenager, but he sounds like an old man. He identifies the worst part of Battle School: Training child soldiers ruins their lives. They no longer behave like children. Their lives are full of pressure and violence.

After the fight with Bonzo, Ender comes to this conclusion. He learned this from Peter: be able to kill or you will get killed. This mentality is what the International Fleet officers want in Ender. It is later echoed by Graff when he justifies humanity's war against the buggers.

This is how Ender interprets Graff's explanation of the war against the buggers. Ender's simple statement is, on some level, an accurate description of many wars in human history: When the two sides cannot communicate effectively any longer, war occurs.

Mazer Rackham, hero of the previous bugger war and Ender's new teacher, gives Ender this warning. The enemy is the one who can best teach Ender. This is an interesting variation of Ender's theory that adults are the enemy. Mazer says a teacher must be an enemy for a student to learn.

10.

Humanity does not ask us to be happy ... Survival first ... happiness as we can manage.

Mazer sacrificed his own happiness and life with his family to train Ender. He says this is what was required to ensure humanity's survival. This also means Ender cannot complain. There is no room for complaints if survival comes before happiness.

Ender sees his "final examination" as an unfair battle just like his last Battle School battle. He decides to play recklessly as he did then. He has no idea he is fighting an actual battle and his "unfair" play will get humans and buggers killed.

12.

Any decent person who knows what warfare is can never go into battle with a whole heart.

Mazer and Graff explain why they tricked Ender into fighting. They made it look like a game so Ender would take chances a "decent" person would not take in a real battle. They couldn't allow themselves to consider what it would do to Ender.

13.

All his crimes weighed heavy on him ... Stilson and Bonzo no heavier ... than the rest.

While most of humanity thinks these two human deaths are particularly horrifying, Ender sees them as less terrible than the deaths of the entire bugger population. Most humans don't care about bugger deaths, but Ender does.

When Ender finds the queen bugger pupa, he sees her thoughts. The buggers forgive humanity and give their planets to the humans, telling Ender the humans will take responsibility for their home now. This remarkable forgiveness and generosity inspire Ender to write Speaker for the Dead and give his life new purpose.
